background: fine needle aspiration (fna) has led to a decrease in unnecessary surgeries for thyroid nodules. this study was designed to compare diagnostic value of fna and frozen section methods in the follicular lesions. methods: this is a cross-sectional study based on the medical records of 42 patients who were referred to surgery clinic of rasool-e-akram hospital in tehran with complaint of...

Introduction localized thyroid enlargement with rest of the thyroid apparently normal is clinically defined as solitary nodule of thyroid. STN is seen in 4-6% of the adult individuals. Fortunately the likelihood that a single thyroid nodule is malignant is approximately 5%. Nodules decreasing in size have negligible risk of cancer and no treatment is required. However, enlarging solid nodules h...

PURPOSE To evaluate the effects of ultrasonography (US)-guided interstitial laser photocoagulation (ILP) on the volume of benign solitary solid cold thyroid nodules and any nodule-related symptoms. MATERIALS AND METHODS ILP was performed in 16 patients with normal thyroid function and a solid benign thyroid nodule. None of the patients had uptake on a radionuclide scan. Patients underwent one...

BACKGROUND The controversy that iodized salt may increase the risk of thyroid disorders has arisen in China during the past several years. OBJECTIVE This study aimed to explore whether iodized salt increased the risk of thyroid nodule among a Chinese population. DESIGN A cross-sectional study was conducted in Hangzhou, China, in 2010. Iodized salt intake, urinary iodine concentration (UIC),...

Heterogeneous features of thyroid nodules in ultrasound images is very difficult task when radiologists and physicians manually draw a complete shape of nodule, size and shape, image or distinguish what type of nodule is exist. Segmentation and classification is important methods for medical image processing. Ultrasound imaging is the best way to prediction of which type of thyroid is there. In...

Thyroid nodules in children are uncommon but often present an increased risk of malignancy in comparison to their adult counterpart. Multiple diagnostic modalities are frequently employed to characterize these nodules including ultrasound, radionuclide scans, fine needle aspiration (FNA), thyroid function tests, and evaluation of patient demographics. We chose to evaluate if any of these modali...

We report a case of a young Indian male who had an incidental abnormal focal uptake of 99mTechnetium-MIBI (Methoxy Isobutyl Isonitrile) in the right lobe of thyroid while undergoing 99mTc-MIBI myocardial perfusion gated SPECT (Single Photon Emission Computed Tomography) imaging as a part of his myocardial ischemia status evaluation. This focal uptake was eventually detected to be a malignant th...

The aim of this paper is to review the radiological evaluation of thyroid nodules detected with ultrasonography (US), thoroughly and in harmony with the clinical-endocrinological-surgical management. In this review, we tried to summarize the radiological evaluation of nodules detected in the thyroid in compliance with recently published and accepted guidelines, including the most advanced sonog...

Thyroid nodules, with their high prevalence in the general population, represent a diagnostic challenge for clinicians. Ultrasound (US), although absolutely reliable in detecting thyroid nodules, is still not accurate enough to differentiate them into benign and malignant. A promising novel modality, US elastography, has been introduced in order to further increase US accuracy. The purpose of t...

in 30 patient with single cold thyroid nodule and normal thyroid function tests, 99mtc-mibi scan is performed. the nodules are divided to hot (10), warm (12) and cold (8). fna reported papillary ca in 4, suspicious follicular neoplasm in 3 and 23 benign lesions. 7 patients were operated on and had final pathology reports (4 papillary ca and 3 benign lesions). all the nodules with no mibi uptake...
